- do not hardcode distfile extension for lang/python ports in bsd.python.mk
(PYTHON_DISTFILE variable)
- switch lang/python ports (and it's slaves) to tar.xz
I compared all the four pairs .tgz/.tar.xz and they have no content differences.

Introduce two new versions of Python: 2.6 and 3.0rc1 (finally!)
Python 2.6 will be the next default python version when enough
testings of consumer ports are done. The new "2to3" program is
renamed to 2to3-2.6 and 2to3-3.0 for each version, respectively.
